Thanks for the quick response,
you are right. It seems that the filter
MPEG2TransportStreamFromPESSource does not generate correct PCR data, as
the ts file generated with the sample overflows vlc also. If I open the
out.ts file with VLC , the messages window fills with "main debug:
waiting decoder fifos to empty" messages. Also, if i stream the ts file
with testMpeg2TransportStreamFramer the result is the same, it sends
with about 50Mbps instead of 6Mbps which is the correct bitrate. If I
pass a ts file created with a third party muxer to
testMpeg2TransportStreamFramer it seems to work ok.

When this happens, it's usually because your 'framer' object is not
able to compute the duration of each Transport Packet (and so, each
packet gets the default duration of 0). The reason for this is
probably that your "MPEG2TransportStreamFramer" is not finding PCRs in
the Transport Stream data.
What I do is basically this:
{
ByteStreamFileSource* fileSource
= ByteStreamFileSource::createNew(*env, inputFileName);
if (fileSource == NULL) {
*env << "Unable to open file \"" << inputFileName
<< "\" as a byte-stream file source\n";
exit(1);
}
MPEG2TransportStreamFromPESSource* tsFrames;
MPEG2TransportStreamFramer* tsFramer;
FramedSource* esVideoSource;
MPEG1or2Demux* baseDemultiplexor = MPEG1or2Demux::createNew(*env,
fileSource);
MPEG1or2DemuxedElementaryStream *videoES =
baseDemultiplexor->newRawPESStream();
tsFrames = MPEG2TransportStreamFromPESSource::createNew(*env,
videoES);
tsFramer = MPEG2TransportStreamFramer::createNew(*env, tsFrames);
This looks good. However, you should first try just converting the
Program Stream file into a Transport Stream file, e.g., using our
"testMPEG1or2ProgramToTransportStream" demo application (whose code
you have adapted).
I.e., first try to generate a Transport Stream file from your Program
Stream file. Then, try to stream that file. That may give you some
insight into what is going wrong.
